step two: the control module starts to control the ultrasonic detector to detect the road condition in front, the judgment method for judging the road condition in front by the ultrasonic detector is to judge according to the size of the ultrasonic back-and-forth walking path S, and the numerical value of S is automatically calculated by the system according to the height and the inclination angle of the position where the sound wave is measured and arranged on the vehicle;
step three: when the system detects that the actual distance S1 of the ultrasonic wave back and forth is less than S, the front part is judged to be provided with a bulge, the control module starts to control the automobile oil pump to reduce the oil supply quantity to the automobile, and simultaneously the automobile brake pump starts to decelerate and brake the automobile; when the system detects that the actual distance S1 back and forth by the ultrasonic wave is equal to S, the system judges that the front part is flat; when the system detects that the actual distance S1 of the ultrasonic wave back and forth is greater than S, the front pit is judged to be formed, the control module starts to control the automobile oil pump to reduce the oil supply quantity to the automobile, and meanwhile, the automobile brake pump starts to decelerate and brake the automobile;
step four: the data processing center compares the information of the actual S1 value fed back by the ultrasonic wave with the standard S value automatically calculated by the system, when the numerical value of | S1-S | is larger, the numerical value of the negative acceleration of the system is larger, and when S1= S, the automobile keeps the original constant-speed cruising speed;
step five: when the data processing center receives a high-grade map through the Internet to prompt that road repair or traffic jam exists in the front of 1-2 kilometers, the system automatically sends out a voice prompt; when the distance is within 0.5-1 kilometer, the system automatically judges whether the constant speed cruise is released or not, and enters a manual operation state;
step six: when the system does not detect that the constant-speed cruising is released and the system enters a manual operation state, if the system detects that the place where the vehicle is repaired or blocked ahead is within the range of 0.5-1 kilometer, the control module starts to decelerate the vehicle to 60 kilometers per hour and keeps the vehicle moving forward at a constant speed of 60 kilometers, and sends out a voice prompt; if the system detects that the distance from the front to the road repairing or traffic jam place is 0.1-0.5 kilometer, the control module starts to decelerate the automobile until the automobile stops moving, and sends out a voice prompt;
step seven: the automobile can automatically start the double flashing lamps to prompt the rear vehicle when the control module automatically controls the automobile to automatically decelerate.
Further: wherein the calculation formula of the pit depth or the height of the bump is as follows: the value of | S1-S |/2, the larger the calculated value, the larger the pit depth or the height of the protrusion.
Further: the ultrasonic wave contain more than 2, the vertical equipartition is installed at the front end of car. And when S1 detected by the Nth ultrasonic wave to the (N + Z) th ultrasonic wave is not equal to a standard value S, automatically calculating the horizontal distance L3= Z L1 at the front end and the rear end of the pit or the bulge and the horizontal distance L2= N L1 between the automobile and the pit or the bulge in front by the system.
Further: the system automatically combines the calculated values of L2 and L3 and the current speed P of the automobile cruising at constant speed to automatically calculate the value of the negative acceleration of the automobile to be decelerated, and ensures that the amplitude of the vibration of the automobile passing through the pit or the bulge is within a point range. When the automobile is cruising at a constant speed, if the system detects that the accelerator is operated manually, the constant-speed cruising state is automatically released, and the automobile is controlled to advance manually.
The invention has the beneficial effects that:
when the automobile enters the constant-speed cruise, the speed of the automobile can keep a certain speed to move forwards without stepping on an accelerator by feet, and at the moment, a driver feels that the automobile easily gives up the alertness of the automobile driving to cause some traffic accidents, so the speed of the automobile can be automatically controlled by automatically identifying road conditions, controlling the automobile constant-speed cruise system to automatically detect the road conditions in front through ultrasonic waves and detecting the road conditions by combining a high-grade map of the Internet, reducing the vertical amplitude of the automobile during running and preventing the traffic accidents such as rear-end collision.
